However, in some embodiments, the general shape of the housing 16 may be different, for example, the housing 16 may be oval, square, or circular.

  The housing 16 includes a top surface 20, a bottom surface 22 located on the opposite side of the top surface 20, and two longitudinal side surfaces 24 and 26. The two longitudinal side surfaces 24, 26 extend longitudinally along the longitudinal axis XX between the top surface 20 and the bottom surface 22. For example, the bottom surface 22 is configured to be disposed in front of the handle 14, and the top surface 20 is disposed on the opposite side of the bottom surface 22. The top surface 20 and the bottom surface 22 are parallel to each other.

  The first longitudinal side surface 24 (also referred to as the front longitudinal side surface 24) and the second longitudinal side surface 26 (also referred to as the rear longitudinal side surface 26) face each other. The second longitudinal side surface 26 is substantially parallel to the first longitudinal side surface 24, particularly when the two longitudinal side surfaces 24, 26 are flat. However, the two longitudinal sides 244, 26 may have a slight or significant slope in opposite directions relative to each other. The first longitudinal side surface 24 and the second longitudinal side surface 26 respectively extend in the longitudinal direction Z along the transverse axis ZZ between the top surface 20 and the bottom surface 22 of the housing 16. Yes. The transverse axis ZZ intersects the longitudinal axis XX. For example, the longitudinal axis XX and the lateral axis ZZ are orthogonal to each other.

  The housing 16 also includes a first lateral side 28 and a second side that extend along the transverse axis YY between the first longitudinal side 24 and the second longitudinal side 26. The lateral side surface 30 is provided. The transverse axis YY is, for example, perpendicular to the longitudinal axis XX and the transverse axis ZZ. The first lateral side surface 28 and the second lateral side surface 30 are disposed in the lateral direction Z between the top surface 20 and the bottom surface 22. The first lateral side surface 28, the second lateral side surface 30, the first longitudinal side surface 24, and the second longitudinal side surface 26 together form the outer surface of the housing 16.

  The housing 16 comprises a plastic material. However, other materials can be used. For example, the housing 16 includes a metal material. Furthermore, the housing 16 may be made of a combination of a plurality of different materials. For example, a portion of the housing 16 is made from a first material and the remaining portion of the housing 16 is made from a second material.

  The housing 16 includes a shaving blade receiving portion 32. The shaving blade receiving portion 32 or the shaving blade receiving area has a general shape that is rectangular when viewed from above. The shaving blade receiving portion 32 is disposed on the top surface 20 of the housing 16. The shaving blade receiving portion 32 forms a recess and is configured to receive the cutting element 18. More specifically, the shaving blade receiving portion 32 is configured to receive at least one cutting element 18. 1 and 8, the shaving blade cartridge 10 includes three cutting elements 18. However, in other embodiments, the shaving blade cartridge 10 includes more or fewer than three cutting elements 18. For example, the shaving blade cartridge 10 may include five cutting elements 18.

  The cutting element 18 is between the first longitudinal side 24 and the second longitudinal side 26 of the housing 16 and between the first lateral side 28 and the second lateral side 30 of the housing 16. Mounted within the formed shaving blade receiving portion 32 and within the housing 16. Each cutting element 18 extends in the longitudinal direction along the cutting axis CC. For example, the axis of the cutting element 18 coincides with the longitudinal axis XX. The cutting axis CC is parallel to the longitudinal axis or inclined with respect to the longitudinal axis XX. Each cutting element 18 includes a first end and a second end disposed along a cutting axis CC. The first end of the cutting element 18 is directed toward the first lateral side 28 of the housing 16, and the second end of the cutting element 18 is directed to the second lateral side 30 of the housing 16. Is directed towards. Each cutting element 18 includes a cutting edge 34. The cutting edge 34 extends along the cutting axis CC. The cutting edge 34 of the cutting element 18 is accessible on the top surface 20 of the housing 16 for cutting the hair during shaving.

  For example, the cutting element 18 is an L-shaped cutting element shown in FIGS. Accordingly, the cutting element 18 has a cutting edge 35, a guide portion 36, and a bent portion 38 located between the cutting edge 35 and the guide portion 36. The cutting element 18 includes a cutting edge portion (that is, a blade element) 35 fixed to the blade support portion 39, and the blade support portion 39 includes a guide portion 36 and a bent portion 38.

  Each cutting element 18 can be freely attached to the housing 16. More specifically, the cutting element 18 is movably attached to the shaving blade receiving portion 32. Each cutting element 18 is supported, for example, by two elastic fingers. The resilient fingers are integrally formed with the housing 16 and may extend within the shaving blade receiver 32 toward each other and upwardly from each of the lateral side surfaces 28, 30 of the housing 16. The guiding part 36 of the cutting element 18 is slidably guided in a slot provided in the housing 16. When the blade element 35 is in contact with the blade support 39, the blade support 39 is provided with elastic fingers.

  However, in some other embodiments (not shown), the cutting element 18 is a bent or curved blade as disclosed, for example, in WO 2013/050606.

  The cutting element 18 is held inside the housing 16 by a retainer 40. In practice, as shown in FIGS. 1 and 8, the shaving blade cartridge 10 includes two retainers 40 that retain the cutting element 18 within the housing 16. For example, the two cages 40 are the same. However, the two retainers 40 may be different, for example, having different dimensions, different shapes, or different arrangements. It should be noted that the following description relates to one retainer but applies to one or two retainers 40.

  The retainer 40 has an inner surface that extends toward the cutting element 18. The retainer 40 extends along the transverse axis YY.

  The retainer 40 includes a portion in front of the cutting element 18. More specifically, the retainer 40 includes a portion facing the cutting edge 34. The portion of the cage 40 in front of the cutting edge 34 forms an inner surface 41 of the cage 40. The inner surface 41 is provided with a rough pattern configured to cooperate with the cutting element 18. The inner surface 41 is flat and / or smooth, and a relief pattern (or a non-smooth pattern 42) is applied to the inner surface 41 of the cage 40. The non-smooth pattern 42 is a groove, a bulge, a cavity, a wedge part, a fulcrum part, or another part that is not continuous with an adjacent part of the inner surface 41. In other words, the non-smooth pattern 42 of the retainer 40 extends outward or inward beyond the adjacent portion of the inner surface 41 of the retainer 40. For example, discontinuous portions exist on the two side surfaces of the non-smooth pattern 42.

  In addition, the retainer 40 includes an outer surface 43 located on the opposite side of the inner surface 41. The outer surface 43 or at least a portion of the outer surface 43 faces the user's skin when shaving with the cutting element 18. The outer surface 43 of the cage 40 is smooth and / or flat.

  As illustrated, the shaving blade cartridge 10 includes a plurality of cutting elements 18, and the plurality of cutting elements 18 are provided with a plurality of non-smooth patterns 42. More specifically, in one embodiment, a non-smooth pattern 42 is provided for each cutting element 18. In some embodiments, a plurality of non-smooth patterns 42 are provided for each cutting element 18.

  The non-smooth pattern 42 extends along the cutting axis CC of the cutting element 18. The cage 40 has a width “w” along the cutting axis CC. In one embodiment depicted in FIGS. 6A and 6B, the non-smooth pattern 42 extends along the entire width of the cage 40.

  7A and 7B, the non-smooth pattern 42 extends along part of the width of the cage 40. The non-smooth pattern 42 controls the movement of the blade element 35 along the cutting axis CC.

  As shown in FIGS. 2 and 3, in the first embodiment, a part of the retainer 40 in front of the cutting edge 34, that is, the inner surface 41 of the retainer 40 disposed in front of the cutting edge 34 is a groove. It has. The non-smooth pattern 42 is formed by a groove.

  As shown in FIG. 2, a groove is provided for each cutting element 18 such that the cutting edge of each cutting element 18 extends within a groove formed in the inner surface of the retainer 40. The cutting edge extends inside the groove. The shape of the groove is complementary to the shape of the cutting element 18. For example, as shown in FIGS. 2 and 3, the groove has a V-shaped cross section, and the tip of the V-shaped cross section corresponds to the tip of the cutting element 18. The cutting element 18 is tapered toward the cutting edge, and the shape of the groove is complementary to the shape of the cutting element 18. The groove has a “control” function, for example, limiting the movement of the cutting element 18 during shaving and / or ensuring a constant distance between the cutting edges. The groove is configured to prevent the cutting edge from moving beyond the rest position of the cutting edge (i.e., the position when no external force is acting on the cutting element 18). For example, the groove has a first wall 48 (ie, a vertical wall) that is perpendicular to the inner surface of the retainer 40 and a second wall 50 (ie, an inclined wall) that has an inclined shape. ing. The vertical wall 48 prevents the cutting edge from moving beyond the rest position of the cutting edge in a direction opposite to the direction toward the bottom surface 22. The inclined wall 50 of the groove allows the cutting element 18 to move toward the bottom surface 22 of the housing 16 and return to the rest position of the cutting element 18 when the cutting element 18 returns from movement during shaving. When the groove 42 does not completely pass through the full width 'w' of the retainer 40 as shown in FIGS. 7A and 7B, the tip of the cutting element 18 collides with the groove 42, and therefore, along the cutting axis CC. The movement can be controlled.

  In practice, the cutting element 18 is pressed against the bottom surface 22 of the housing 16 as the user's skin exerts a force on the cutting element 18 during (or just before) shaving. Thus, the cutting element 18 should not contact the retainer 40 during shaving. By means of the inclined wall 50 of the groove, the cutting element 18 is moved towards the bottom surface 22. If no force is applied to the cutting element 18 after shaving, the cutting element 18 is such that the cutting element 18 is in contact with the retainer 40 and the cutting edge 34 extends into the groove 42. Finally, it returns to the 18 rest position.

  The cage 40 has a thickness “t” along the transverse axis ZZ, and the groove extends inside the thickness of the cage 40. For example, the depth of the groove is less than 50% of the thickness of the cage 40. The thickness of the groove may be less than 35% of the thickness of the cage 40.

  In the second embodiment shown in FIG. 4, a raised portion is provided on the inner surface of the cage 40. Accordingly, the non-smooth pattern 42 is formed by the raised portions. The raised portion protrudes from the inner surface of the cage 40, specifically, the cage body. The ridges may be hemispherical or may be beams or ribs along the width “w” of the cage 40. The raised portion is formed integrally with the retainer 40. In one embodiment, the ridge is an additional part. In this case, the raised portion is welded or bonded, or is attached to the cage 40.

  More specifically, as shown in FIG. 4, the raised portion is provided corresponding to each cutting element 18. The ridge is offset from the cutting edge 34 such that the ridge is located between the cutting edge 34 and the guide portion 36 of the cutting element 18. In other words, the raised portion is disposed at a non-zero distance from the cutting edge 34 along the transverse direction Y-Y. The ridge may abut a portion of the cutting element 18 or a ridge support provided on the cutting element 18 such that the ridge limits the rotational movement of the cutting element 18 during shaving. Yes.

  In the third embodiment shown in FIG. 5, both the raised portion and the groove are provided on the inner surface of the cage 40. Therefore, the non-smooth pattern 42 is formed by a combination of a raised portion and a groove. The groove is continuously arranged on the raised portion such that the raised portion and the groove form an inclined surface. The inner surface 41 of the cutting element 18 abuts the ridge, while the tip of the cutting element 18 cooperates with the groove.

  The shaving blade cartridge 10 includes two holders 40. The non-smooth pattern 42 of the first holder 40 and the non-smooth pattern 42 of the second holder 40 may be the same or different. For example, the first clip has a non-smooth pattern 42, but the second clip does not have a non-smooth pattern 42.

  For example, the non-smooth pattern 42 of the first retainer 40 and the non-smooth pattern 42 of the second retainer 40 have the same length and extend along the cutting axis CC. In other words, the direction in which the non-smooth pattern 42 of the first holder 40 extends is the same as the direction in which the non-smooth pattern 42 of the second holder 40 extends. When the non-smooth pattern is a groove, the groove of the second cage 40 extends along the same direction as the groove of the first cage 40.

  As shown in FIGS. 1 and 8, the retainer 40 is a clip. In addition, the shaving blade cartridge 10 includes two holders or two clips.

  Since the distance between the two clips is shorter than the length of the cutting element 18, each of the first clip and the second clip has a portion located in front of the cutting element 18. A portion of the first clip and the second clip located in front of the cutting element 18 holds the cutting element 18 and includes a non-smooth pattern 42. The portion of the first clip and the second clip located in front of the cutting element 18 is when the cutting element 18 is in the rest position (ie, when no external force is acting on the shaving blade cartridge 10). In contact with the cutting element 18.

  Furthermore, the retainer 40 (ie, the clip) includes an aluminum alloy material. The cutting element 18 comprises an alloy steel material.

  For example, each of the clips shown in FIGS. 1 and 8 includes a first leg, a second leg, and a clip body 45. The clip main body 45 extends between the first leg portion and the second leg portion. The clip main body 45, the first leg portion, and the second leg portion are integrally formed. The clip is made of a moldable material, such as a thin sheet of suitable material. However, other materials may be used. Preferably, the width of the clip is constant along the length of the clip. The clip is made of a metallic material, for example a thin metal. In one embodiment, the leg of the clip surrounds the first longitudinal side 24 of the housing 16 and at least a portion of the bottom surface 22 of the housing 16. In other words, a portion of the clip surrounds a portion of the housing 16. In some cases, the leg of the clip is received in a through hole provided in the housing 16.

  However, the cage 40 may have other shapes. For example, the retainer 40 is fixed to the housing 16 by fitting or press fitting, or is welded to the housing 16. The retainer 40 has a body facing the cutting element 18 but may not have legs. The holder 40 may be held in the housing 16 by rivets.

  The shaving blade cartridge 10 includes a guard 44. The guard 44 is arranged in front of the cutting element 18. More specifically, the guard 44 is arranged in front of the cutting element 18. The guard 44 is disposed toward the first longitudinal side 24 (the first longitudinal side 24 is also referred to as the rear longitudinal side). The guard 44 extends along the longitudinal axis XX.

  The shaving blade cartridge 10 includes a cap 46. The cap 46 is disposed behind the cutting edge 34. The cap 46 is disposed toward the first longitudinal side surface 24. For example, the cap 46 is provided on the rear element. The rear element has a T-shaped or U-shaped configuration in which the legs of the rear element are mounted inside the housing 16. The legs are press-fitted or fitted into the housing 16. However, in other embodiments, the posterior element is secured to the housing 16 by other methods or means such as gluing or overmolding.
